The measurement of the surveying and mapping in mine
Since the seventy s, as the electronic technology and laser technology development, the type of surveying and mapping instruments with electronics (such as range finder, electronic tachometer, gyroscopes) to the traditional surveying and mapping instruments methods produced profound effect. In satellite remote sensing, global positioning system, as a representative of the space on earth observation technology in surveying and mapping application in the science of mature, computer technology, system scientifically based geographic information system and application for the emergence of surveying and mapping information source of access, analyze, management, processing and application fully provide strong technical support, automation and intelligence of surveying and mapping system is already in investigation, therefore we can say, the modern mapping technology is undergoing a profound revolution. Mining of measuring technology of an important application field, in the vast coal, metal mines, nonferrous mine production process played an important role. Mine survey of modern task is: in mine exploration, design, development and production of the different stages of the operation of the ground and underground mining area, the space, resources, (in mineral and land resources and environment are mainly) information acquisition, storage, processing, display and use for reasonable and effective development resources, protecting the resources, protecting the environment, management, industrial and environmental services for the continuous development of the station. In order to realize its modern task, mine measurement must be making full use of modern surveying and mapping instruments and techniques, put the advanced modern technology with mine surveying the actual work, specific characteristics, and the combination of broaden the living space mine survey and business scope, promote the reform and development of mine survey, adapt to the market economy system and mining system reform needs. Electronic tachometer, space information technology, the inertial measurement system and other modern surveying and mapping instruments have been in mine survey technology is used to further development and are constantly.
This paper to modern surveying and mapping instruments of the development of the technology and its application in mine
1、Electronic tachometer as the most widely used surveying and mapping instruments, is electronic technology and optical technology development of the combination of the photoelectric measuring instrument, is also set range finder, electronic advantages in a wide range of instruments, application prospects, the intelligent electronic tachometer is currently the biggest selling surveying and mapping instruments, is also the main future development direction. Intelligent electronic tachometer is with light, electricity and magnetism, machine of the latest scientific achievements, set the location, measuring Angle for the integration of advanced instrument. The international advanced electronic tachometer are on a memory card, internal memory or electronic hand book way, way of double record data transmission communication function, can receive external computer instruction by the computer input data, also can to outside the computer output data. The international advanced electronic tachometer have Japanese SOKKIA POWERSET series production of electronic tachometer and SET5F, SET6F, SET5W electronic tachometer, Swiss produces the TCA100 and TCA1800 electronic tachometer, Japan NIKON DTM-A series of electronic tachometer, etc. Our country has just south of the surveying and mapping instruments company production NTS-200 series electronic tachometer. Electronic tachometer has set up a file in the engineering survey, mine surveying, cadastral etc a wide range of applications, its development and application is in rapid developing. Electronic tachometer because and has the advantages of transit and range finder, and provide measurement results in digital form, its simple operation, stable performance, data can be through the electronic hand book and the computer to carry on the advantages of communication in the mine in the measurement of a wide range of applications. The ground control survey, topographic, engineering surveying all available is, contact measurement, the measurement work can also be used in
underground i To as a representative of the intelligent, digital instrument is mine surveying instrument one of the development direction in the future. Based on the electronic tachometer and the modern computer technology can establish a mine 3 d data to be automatic collection, transmission, processing of mine surveying data processing system, instead of traditional hand book records, manual entry, detailed
calculation of repetitive work. In addition, electronic tachometer in mine surface movement monitoring, land reclamation project implementation, mine construction aspects also have been applied, each big ore measurement organizations are to instead of traditional instruments for routine measure the work, not only improves the efficiency, picked up speed, and reduced the development, and to ensure the accuracy
2、Space information technology and its application in the measurement of
the mine.The core of spatial information technology and the subject is the \S\technology (ＲｅｍｏｔｅＳｅｎｓｉｎｇ：ＲＳ)、 (ＧｌｏｂａｌＰｏｓｉｔｉｏｎｉｎｇＳｙｓｔｅｍＧＰＳ)、 (ＧｒｏｇｒａｐｈｉｃＩｎｆｏｒｍａｔｉｏｎＳｙｓｔｅｍ：ＧＩＳ) Remote sensing including satellite remote sensing and remote sensing, remote sensing data topographic map surveying as the important means in practice has a wide range of applications, satellite remote sensing for mapping is also mine of study and has made some significant results, based on remote sensing data to build digital terrain model (DTM) and then used in surveying and mapping work has won more applications. GPS as a cause of surveying and mapping in the traditional concept of major change technology, has become a main technology of land measurement method, also is the most potential mobile technology, in mine measurement, control survey, project survey, environment monitoring, disaster prevention and reduction of the navigation transport plays a significant role. Because not only have all-weather GPS, high precision and high flexibility, and the advantages of the traditional measuring technology without strict control, compared the level measurement, don't take points between depending on the point, without the need to build standard, there is no error accumulation, the three dimensional positioning etc, and in the field measurement model, error sources and data processing to the traditional concept of surveying and mapping is a revolutionary change. The geographic information system as the geographical distribution of space of the relevant data collecting, processing, management, analysis of computer technology system, and its development and application of surveying and mapping the development of science is of great significance, is the modern mapping technology of important technical support. With \S\integration or integrated as the leading technology of space information system has gradually become the surveying and
